Question

This is for Windows Phone 7.5

I am not able to remove menuitems from my contextmenu based on the pivotitem. I have three pivotitems and I need to show the custom items in the context menu.

I am trying to find the right event that can help me capture the current pivot item and based on that I would like to present context menu options.

Update #1:

Xaml Markup:

 <controls:PivotItem x:Name="HighPivotItem" Header="high">
        <toolkit:ContextMenuService.ContextMenu>
            <toolkit:ContextMenu Opened="ContextMenu_Opened" 
                           Closed="ContextMenu_Closed">
                <toolkit:MenuItem Header="mark as done" Click="MarkMenuItem_Click"/>
                <toolkit:MenuItem Header="edit" Click="EditMenuItem_Click"/>
                <toolkit:MenuItem Header="delete" Click="DeleteMenuItem_Click"/>
            </toolkit:ContextMenu>
        </toolkit:ContextMenuService.ContextMenu>
        <Grid>
            <TextBlock x:Name="HighTextBlock" Text=""
      Visibility="Collapsed" Margin="22,17,0,0"
 Style="{StaticResource PhoneTextGroupHeaderStyle}" />

            <ListBox x:Name="HighListBox" 
             ItemTemplate="{StaticResource DataTemplate}"
             SelectionChanged="ListBox_SelectionChanged" />
        </Grid>
    </controls:PivotItem>

Here is the code in my event:

void MarkMenuItem_Click(object sender, RoutedEventArgs e)
{
  Task task = (sender as MenuItem).DataContext as Task;

  // Move from the task list to the done list
  Settings.TaskList.Value.Remove(task);
  Settings.DoneList.Value.Add(task);

  RefreshLists();
}

You should be designing your context menus per pivot item

        <controls:Pivot Title="Pivot">
            <controls:PivotItem Header="one" DataContext="{Binding Task}">
                <!-- Stuff for pivot ONE -->
                <toolkit:ContextMenuService.ContextMenu>
                    <toolkit:ContextMenu >
                        <toolkit:MenuItem Header="Menu for both"/>
                        <toolkit:MenuItem Header="Menu for item ONE"/>
                    </toolkit:ContextMenu>
                </toolkit:ContextMenuService.ContextMenu>
            </controls:PivotItem>
            <controls:PivotItem Header="two">
                <!-- Stuff for pivot TWO -->
                <toolkit:ContextMenuService.ContextMenu>
                    <toolkit:ContextMenu >
                        <toolkit:MenuItem Header="Menu for both"/>
                        <toolkit:MenuItem Header="Menu for item TWO"/>
                    </toolkit:ContextMenu>
                </toolkit:ContextMenuService.ContextMenu>
            </controls:PivotItem>
        </controls:Pivot>

The menus can be placed into a datatemplate for a listbox, or onto individual items.

The example above assumes that the page has a DataContext that has a property “Task”

public MainPage()
{
    this.DataContext = new ViewModel { Task = new Task() };
    InitializeComponent();
}
